So I have been debating and researching, even looking for a "cheap" used refrigerated air dryer. Aftercoolers go between the compressor and tank. What is being suggested here is the copper pipe whether it be run vertical with many drains or horizontal with one drain seems to be the consensus. Here is the question I have...instead of running copper pipe on the wall as the cooler...why couldn't I mount a aftercooler (condensor/radiator) after the tank and before my plumbing with a drain? Wouldn't that give the same effect with minimal space taken?
